LRD refers to the thermal relay; C08C has a current rating of 2.4~4, and this is the value of the protection current

For reference only. Trip unit model: Mic2.2. Type of trip unit: Electronic. Function of the trip unit: LSI. Rated current of the trip unit (A): 40/25. Range of setting current for long-time delay protection (A): (0.4~1)In. Range of delay time for long-time delay protection (s): 400 (at 1.5Ir). Range of setting current for short-time delay protection (A): (1.5~10)Ir. Range of delay time for short-time delay protection (s): 80. Range of setting current for instantaneous protection (A): Approximately 15In. Range of setting current for ground fault protection (A). Range of delay time for ground fault protection (s). Communication functions and protocols: Modbus
